Bassam Shakhashiri, a professor at the ultra-liberal University of Wisconsin-Madison and Distinguished Chair of the “progressive” group the Wisconsin Idea, along with his University of Wisconsin-Madison colleague Jerry Bell, write, “Communicating the science of climate change provides one example where the scientific community must do more. Climate change affects everyone, so everyone should understand why the climate is changing and what it means for them, their children, and generations to follow.”

More importantly, we should look at the past several thousand years, rather than merely the past century, when assessing the context of current temperatures. The Earth’s current temperature, when assessed in proper context, is relatively cool right now. Today’s temperatures are cooler than those that prevailed during most of the past 10,000 years, when human civilization first developed and thrived. Temperatures during the past century only seem warm when compared with the Little Ice Age, which brought about the coldest temperatures of the past 10,000 years and ended just over a century ago.

Shakhashir and Bell claim “ice is melting.” If global temperatures finally warm from the extreme cold of the Little Ice Age, we can certainly expect some of the unusually prevalent ice to melt. But is ice melting at an alarming rate? Not according to NASA and NOAA satellite data. In fact, NASA and NOAA satellite instruments show polar sea ice has remained relatively steady since the satellite instruments were launched in 1979, and polar sea ice is currently more extensive than the long-term average.

Shakhashir and Bell claim “oceans are acidifying.” The oceans are alkaline, not acidic. The oceans have a pH of 8.1, which is far above the neutral pH of 7.0. To the extent ocean alkalinity may have declined from 8.2 to 8.1 during the past century, the oceans are becoming less alkaline, not more acidic.

Shakhashiri and Bell assert we should have more climate change conversations. I agree, especially considering the scientific evidence debunks global warming alarmism. Messieurs Shakhashiri and Bell, you name the time, place and venue, and I will be happy to oblige you in considering this climate change conversation.
